AUTOMATIC PLAYING MECHANISM FOR MUSICAL INSTRUMENTS.

Specification of Letters Patent.

Patented Jan. 1 5, 1907.

Application filed September 15, 1905- Berial No 2| 8.559.

To all whom it may concern.-

Be it known that I, CHARLES B. DUNOTT, of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Automatic Playing Mechanism for Musical Instruments, whereof the following is a specification, reference being had to the accompanying drawings.

My invention may be employed with particular advantage in pianos, organs, and similar instruments comprising automaticplaying mechanism permanently adjusted in operative relation with their soundingdevices for instance, mechanism of the kind comprising a series of pneumatic motors or strikepneumatics, respectively in operative relation to the individual sounding devices and having individual valve mechanisms controlled by a web of perforated paper which is progrossed with respect to a pneumatic trackerbar provided with a series of apertures cor-, responding with a series of sounding devices in the instrument.

My improvements relate particularly to means for operatively connecting the blowing mechanism with its pedal mechanism and to rigidly secure the same within the casing of a musical instrument.

The form of my invention hereinafter described comprises brackets arranged to support both the blowing mechanism and the pedal mechanism in removable connection with the instrument-casing, and the pedal mechanism is pivotally supported by said brackets and arranged to extend without the casing when in operative relation with the blowing mechanism and to be folded within said casing on said pivotal supports when in idle position.

My invention includes the various novel features of construction and arrangement hereinafter more definitely specified.

In the accompanying drawings, Figure I is a transverse vertical sectional view of a piano conveniently embodying my improvements. Fig. II is a plan sectional taken on the line 11 II in Fig. I, showing the blowing mechanism and the pedals connected therei with. In said drawings the piano-casing 1 comprises the key-frame 2, on which the digitals 3 are supported by the balance-rad 4. Each i of said digitals 3 is provided with an adjustmusical instrument; of a I porting said panel on said instrument-frame i a pump-bellows supported by said panel; a

able stud 5 and means operatively connecting it with a piano-action, which may be of any convenient construction arranged to strike the string 11 on the metallic stringfrarne I2, which latter is provided with the usual wooden back-sup orts 13 and the sounding-board 15. SaltFcasing I also comprises the usual upper lid 17, the removable front panel 18, inclosing the action, the hinged cover for the manual comprising the digitals 3, and the removable front panel 21, inclosing the chamber 22 below the keyframe 2.' Said chamber 22 is provided with the floor 23, which supports the panel 25 by means of the brackets 28, restingupon the floor in removable relation. The two pumpingbellows are directly attached to said panel 25, as shown in Fig. II, and comprise the leaves 32, having the levers 33, connected by the pivots 34, links 35, and pivots 36 with the pump-pedals 3?. Secured to the panel 25 is the Wind-trunk 42, and supported at opposite ends of the wind-trunk are the reservoir-bellows 43 and 44. Said pedals 37 are supported by pivots 38 on the frame 39, which in operative position (shown in the drawings) has its feet 40 resting on the floor. However, the frame 39 is pivoted on the brackets 28, so that said frame and pedals may be turned within the casing 1 through the doorway, (indicated by the dotted lines in Fig. I, (which maybe closed bysuitable doors. (indicated at 41 in said figure.)

do not desire to limit myself to the precise details of construction and arrangement herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of my invention.

I claim 1. The combination with the frame of a musical instrument; of a panel; brackets supporting said panel on said instrument-frame; a pump-bellows supported by said panel; and, apedal in operative relation with said pump-bellows, supported by said bracket, subfiantially as set forth.

2. The combination with the frame of a panel; brackets suppedfi in operative relation with said pumpbellows and, a frame pivotally connecting ioo said pedal with said brackets, substantially asset forth.

3.,The combination wish musical instrument; of a panel; brackets sup- 5 v porting said'pa neLon said instrument-frame 'a' pump-bellows supported by said panel; a"

edaLin operative relation with said pumpe ows'; and, a 'frame-pivotally Connecting said pedal with said brackets, arranged so 510 that said pedal may be folded in inoperative position, substantially as set forth.-

' 4: The c ombinatiomwith the frame ofamusical instrument; of a panel brackets supporting said panel on said instrument-frame;

the frame of a" a pump-bellows supported by'said panel; a 'pedal connected to said brackets, in operative relation with said pump-bellows a windtrunk secured to said panel; and, a reseryoirbellows supported by said Wind-trunk, substantially as set forth.

In testimony ,whereof I have hereunto signed my name, at Philadelphia, Pennsylyania, this 14th day of September, 1905.
